Five friends who play badminton surveyed the city and collected the price of shuttlecocks across brands and types (Nylon and Feather). The following is the list of the prices, in rupees (₹), that each one compiled. Yusuf: 40(N), 105(N), 383(F), 108(N), 165(F), 116(F) Srikanth: 194(N), 85(N), 93(N), 121(N) Kashvi: 49(N), 297(F), 105(N), 275(F), 40(N) Prasanna: 124(N), 333(F), 182(N), 258(F) Gracy: 220(F), 458(F), 129(F), 183(N) Can you describe a way they can work together to find the average price of a shuttlecock across types? (i) Each one calculated the average of the prices they had gathered. Suppose these are aᵧ, aₛ, aₖ, aₚ, a₉ respectively. Write an expression that gives the combined average. (ii) Suppose aₙ, a𝒻 are the average prices of the nylon shuttlecocks and the feather shuttlecocks, respectively. Write an expression that gives the average price of a shuttlecock. Will this be equal to the answer we got using the method in the previous part?

(i) [(6aᵧ) + (4aₛ) + (5aₖ) + (4aₚ) + (4a₉)] / 23. (ii) With 13 nylon and 10 feather shuttles, the expression is [(13aₙ) + (10a𝒻)] / 23. Yes, both methods yield the exact same overall average. Ganita Manjari part 2 ...

(ii) Is it possible to mix water from the Dead Sea and purified drinking water to get a mixture with the salinity of groundwater? Why/Why not? What quantity of purified drinking water should Dorjee mix with 1 litre of water from the Dead Sea to get a mixture having the salinity of groundwater? (iii) Is it possible to mix water from the Dead Sea and groundwater to get a mixture with the salinity of purified drinking water? Why/Why not? What quantity of groundwater should he mix with 1 litre of water from the Dead Sea to get a mixture having the salinity of purified drinking water?

(i) Salinity is approximately 11.33%. (ii) Yes, because 0.01% lies between 34% and 0.001%; he needs about 3777 litres. (iii) No, because mixture salinity cannot fall below 0.01%. Class 9 Maths How Quantities Combine Understanding Data Question Answer Class 9 Maths ...

The following table shows the weight data of langurs in an animal facility. Without doing any computations, can you tell whether there are more male langurs or more female langurs? Or are they equal in number? (i) Which of the following expression(s) describes the given scenario? (a) (16.5x + 13.8y) / (x + y) = 14.925 (b) (16.5x + 13.8y) / 60 = 14.925 (c) (16.5x + 13.8y) / 2 = 14.925 (d) (16.5x + 13.8y) / (16.5 + 13.8) = 14.925 (ii) Find out how many male langurs are present. (iii) A female langur weighing 15.2 kg is admitted to the facility. What is the average weight of the female langurs after this? (iv) Two male langurs weighing 16.9 kg and 16.1 kg are released from the facility. What is the average weight of the male langurs after this? (v) Now, suppose one of the male langurs lost 1 kg of weight. What is the average weight of all the male langurs after this?

There are more females because 14.925 kg is below the 15.15 kg midpoint. (i) Expressions (a) and (b) are correct. (ii) 25 males. (iii) 13.839 kg. (iv) 16.5 kg. (v) 16.46 kg. Class 9 Ganita Manjari Part 2 All Chapter Solutions
